Toyota finds 10% MPG improvement in hybrid PCU

Keeping up its from-all-angles approach to efficiency, Toyota has found yet another way to eke out up to ten percent more precious MPGs in its hybrid vehicles, this time electronically. The automaker has announced the development of new silicon carbide (SiC) power semiconductors for use in power control units, which it will begin testing on Japanese roads within the next year. The PCU using the silicon carbide compound offers less electrical resistance, which improves efficiency when passing current between the battery and electric motor. It also loses less power after shutting off, and can operate at a higher frequency. The net power loss of the new PCU is just one-tenth of the current silicone-only version (the latter accounting for 20 percent of total electrical power loss in today's hybrids). The result, so far, is a claimed five-percent improvement in fuel economy in test vehicles, with the potential of ten percent by the time the new SiC power semiconductor comes to market. Additionally, the carbide wafers allow for smaller a power module, coil and capacitor, thus allowing the entire PCU to be 80 percent smaller (see the side-by-side comparison in the accompanying photo, which you can click to enlarge). We've got a while to wait before we start to see the carbide technology to start making a real-world impact. Toyota aims to begin using the SiC units in 2020. By then, with improvements in the company's other key efficiency factors - engine technology and aerodynamics - cars like the Prius will likely see significant gains in fuel economy.

Toyota Develops 'Diamond-like' Computer Chips to Boost Hybrid Mileage May 20, 2014 Toyota City, Japan – Toyota is using one of the hardest materials in nature after diamonds to develop a semiconductor chip it hopes will improve the fuel efficiency of its hybrids, such as the Prius, by as much at 10 percent. The company and its partners announced today that they have developed a silicon carbide (SiC) power semiconductor for use in automotive power control units. Toyota plans to begin test-driving vehicles with the technology on public roads in Japan within a year. The chips, made from carbide - one of the hardest materials in nature, theoretically have superior characteristics such as one-tenth the electrical power loss and 10 times the drive frequency. Toyota said the chips would also allow it to reduce the size of current automotive power control units by 80 percent.

Toyota C-HR Concept is a high-riding hybrid hatch [w/video]

Despite having the tendency to offer decidedly bland production cars, Toyota occasionally surprises us with interesting concept cars. Such is the case with the C-HR concept making its debut at the Paris Motor Show this week. It's a concept showing forward-thinking design that hints at "a type of crossover vehicle Toyota would like to bring to market," according to the automaker's release, and it rides on an all-new platform and uses a hybrid powertrain.
About that powertrain: Toyota isn't revealing anything, just saying that it will - brace yourselves - "deliver significantly improved fuel efficiency" (over what, exactly?) The car also uses a brand-new architecture, though it hasn't really revealed any major details about that aspect, either.
It's a high-riding, muscular thing, with a rakish hatchback shape. Should it reach production, Toyota says it would take the shape of a C-segment crossover. It'd be cool to see something like this hit the road someday, but for now, we won't hold our breath.

Toyota to sell hot-pink Crown in Japan

Akio Toyoda is doing a pretty decent job at the helm of the Toyota empire. This is the man, after all, that declared that Toyota would get new sports cars, and that they needed to be, not should be, rear-wheel drive. We can respect that. Toyoda is also trying to do away with his company's conservative styling and bring edgier vehicles to market.
Toyota's designers have done just that, although perhaps they went a bit too far. In November, Toyota debuted its fourteenth-generation Crown with a bling-bling fascia that makes Lexus' spindle grille look as conservative as a three-piece suit, and a retina-searing pink paintjob. See, in Japan, the Crown is to Japan's older crowd what the 2002 Buick Park Avenue is to America's senior citizens. As Automotive News reports, the idea with the pink was to draw attention to the grille, but it was originally intended as a debut item, only.
Now, Toyota is actually planning to offer the electric fuchsia Crown for sale to regular buyers. Interested parties will have from September 1st to September 30th to place an order for the big sedan. According to the AN report, Toyoda said to reporters at the debut, "My initial reaction was: 'You're kidding! Please, not pink." We wish they were kidding.
